Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a Symmetry in biology#Bilate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastropod
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Aplysia Pulmonica
''Aplysia'' () is a genus of medium-sized to extremely large sea slugs, specifically sea hares, which are one clade of large sea slugs, marine gastropod mollusks. These benthic herbivorous creatures can become rather large compared with most other mollusks. They graze in tidal and subtidal zones of tropical waters, mostly in the Indo-Pacific Ocean (23 species); but they can also be found in the Atlantic Ocean (12 species), with a few species occurring in the Mediterranean. ''Aplysia'' species, when threatened, frequently release clouds of ink, it is believed in order to blind the attacker (though they are in fact considered edible by relatively few species). Following the lead of Eric R. Kandel, the genus has been studied as a model organism by neurobiologists, because its gill and siphon withdrawal reflex, as studied in ''Aplysia californica'', is mediated by electrical synapses, which allow several neurons to fire synchronously. This quick neural response is necessary fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aplysia Juliana
''Aplysia juliana'', the walking sea hare, is a species of sea hare, a marine gastropod in the family Aplysiidae. Distribution Distribution of this species is cosmopolitan, circumtropical in all warm seas. Description This sea hare has no purple gland and therefore cannot produce ink, just milky secretions. The posterior end of the foot in this species can act as a sucker. The color of this sea hare is very often brown with paler spots, but it can be various other shades including plain black all over. The maximum recorded length is 300 mm.Welch J. J. (2010). "The "Island Rule" and Deep-Sea Gastropods: Re-Examining the Evidence". '' PLoS ONE'' 5(1): e8776. .

''Aplysia morio'', the Atlantic black sea hare or sooty sea hare, is a species of sea slug, a marine gastropod mollusk in the family Aplysiidae, the sea hares. It lives in warm waters in the Caribbean Sea and off the south and southeastern coast of the United States, where it feeds on seaweed. Description ''Aplysia morio'' is a bulky sea slug that can grow to a length of or more. It is usually dark chocolate brown to blackish in colour, and sometimes dark lines are visible on the head and flanks. The tentacles are curled and shaped rather like rabbit's ears. They are rich in nerve cells and are equipped with receptor organs. The shell is a fragile disc, hidden within the mantle, and the foot has large flaps at the side called parapodia which are used for swimming. Distribution and habitat This species is found in the semi-tropical western Atlantic Ocean. Its range includes the eastern coast of the United States, Bermuda, the West Indies, Florida, the Caribbean Sea, the Gulf of M ...
